■ Features (BLM_R Series)

The chip ferrite beads BLM series is designed to

function nearly as a resistor at noise frequencies,

which greatly reduces the possibility of resonance and

leaves signal wave forms undistorted.

■ Equivalent Circuit

The BLM series is effective in circuits without stable

ground lines because the BLM series does not need a

connection to ground.

The nickel barrier structure of the external

electrodes provides excellent solder heat resistance.

The BLM_R series can be used in a digital Interface.

Resistance of BLM_R series especially grows in the

lower frequency range. Therefore BLM_R series is less

effective for digital signal waveform at low frequency

range and can suppress the ringing.

(Resistance element becomes dominant

at high frequencies.)
